Recent studies have suggested that overexpression of TOMM34, another outer membrane translocase (Nuttall et al, 1997), predicted poor prognosis in a number of cancers including liver cancer (Toraih et al, 2019), colorectal cancer (Zhang et al, 2014), and breast cancer (Aleskandarany et al, 2012). Here, TOMM34 is linked to liver cancer.
